@nickheer Yes, but the keybag is protected by the “iCloud keys,” i.e. ones that Apple has.

@nickheer “Encrypted files copy” just means it doesn’t decrypt before sending over the network. It’s consistent with Apple having the key.

@nickheer It talks about using iCloud password and device passcode to access data if all devices are lost. But that’s not how Backup works.

@nickheer Could be wrong, but I think that whole section is about iCloud Keychain and doesn’t pertain to Backup.

@nickheer Right, but it doesn’t say that Apple doesn’t have that key.

@nickheer Reading between the lines, seems like when you turn on Backup it generates a key and sends it to the iCloud server.

@nickheer Regular iCloud backups can be restored to a brand new device, and p. 46 days it doesn't even use your iCloud password.

@nickheer I think that’s only for the keychain, which is why you can only restore the keychain to the same device.

@nickheer I thought the issue with iCloud backups was that they’re encrypted but Apple can access them. Whereas iTunes can set a password.
